Measures reported by NetCluVserSateTest

A virtual storage server (Vserver) contains data volumes and one or more Logical interfaces (LIFs) through which it serves data to the clients. Starting with clustered Data ONTAP 8.1.1, a Vserver can either contain one or more FlexVol volumes, or a single Infinite Volume.

A Vserver securely isolates the shared virtualized data storage and network, and appears as a single dedicated server to its clients. Each Vserver has a separate administrator authentication domain and can be managed independently by a Vserver administrator.

In a cluster, Vserver facilitates data access. A cluster must have at least one Vserver to serve data.

Vservers use the storage and network resources of the cluster. However, the volumes and LIFs are exclusive to the Vserver. Multiple Vservers can coexist in a single cluster without being bound to any node in a cluster. However, they are bound to the physical cluster on which they exist.

A cluster can have one or more Vservers with FlexVol volumes and Vservers with Infinite Volumes.

    A NetApp Cluster contains the following types of Vservers:

  • Admin Vserver
  • Node Vserver
  • Data Vserver
Vservers provide data access to clients without regard to physical storage or controller, similar to any storage system. When you use Vservers, they provide benefits such as nondisruptive operation, scalability, security and support unified storage. Therefore, continuous availability of the Vserver is essential so that there does not exist any disrutipon in the data transfer and hence, it becomes imperative to monitor the state of the Vservers. This is exactly how the Vserver State test helps!

This test auto-discovers the Vservers configured on the NetApp Cluster and reports the current state of each Vserver.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
State Indicates the current state of this Vserver. Number The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
Running 0
Starting 1
Initializing 2
Stopping 3
Stopped 4
Deleting 5

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current state of this Vserver. However, in the graph of this measure, states will be represented using the corresponding numeric equivalents i.e., 0 to 5.
